Aconcagua (the 'normal route')

This page is under construction

Aconcagua is the highest mountain outside the Himalaya and a much sought-after prize. Extreme altitude and weather conditions make it a major objective for experienced mountaineers and a high altitude trekkers, despite its moderate technical difficulties.

The usual approach is from the south via the Quebrada de los Horcones to the Plaza de Mulas base camp at 4365m. From here, 3 routes start: the 'normal route' via the Horcones Glacier Superior and North East Ridge, the West Buttress route and the South-West route. We'll be going for the normal route.

There's no point in playing-down the physical and mental challenges of climbing Aconcagua. This is not a trek. It is a long, exhausting (and sometimes monotonous) mountaineering expedition... a huge step-up from climbing peaks such as Kilimanjaro and Orizaba. Conditions tend to be far harsher than on other 'popular' high mountains and the summit day is very long and very strenuous. Expect to be pushed to the limit.

It makes sense for aspirant Aconcagua climbers to have served an apprenticeship on other high mountains before taking-up the challenge. Whilst it is possible for inexperienced climbers to make it to the summit, the success rate is low. Those who are able to fall back on several years experience of climbing at high altitude, are self sufficient, familiar with the use of crampons and an axe and aware of how they fare at high altitude are far more likely to be successful.

Aconcagua candidates should:

  • Have a high level of mental and physical fitness, determination and experience of high altitude trekking and mountaineering in extremely cold, windy and arid conditions.
  • Be capable of load-carrying between camps. Expect to carry about 15KG's.
  • Be competent in the use of ice axe and crampons.
  • Be comfortable 'surviving' for long periods of time at high altitude and in harsh conditions. You should be aware of the associated health and hygiene implications and be able to look after yourself.


Part 1: Plaza de Mulas (4300m) - Plaza Canada (5050m). 3 - 4 hours. 750m height gain.

Follow a well defined but steep and rocky path.

Part 2: Plaza Canada - Nido de Condores (5550m). 4 - 5 hours. 500m height gain.

The rocky path continues past the 5000m stone, Cambio de Pendiente and Cerro Manso to reach Nido de Cóndores.

Part 3: Nido de Condores - Refugio Berlin (5930m). 3 - 4 hours. 380m height gain.

This is a short stretch, but the altitude really starts to kick in and progress is slow.

Part 4: Refugio Berlin - Summit (6962m). 7 - 10 hours. 1032m height gain.

EXTREMELY demanding. Expect high winds and very low temperatures. Crampons often needed.

The main challenge is the infamous Canaleta a steep, scree slope which is encountered at high altitude when physical and mental toughness is being tested to the limit. Progress often becomes extremely slow here. Beyond the Canaleta…lies the summit!
